3. Raw meal homogenization In the production of new dry process cement, stabilizing raw material composition in pit is the precondition of stabilizing clinker firing thermal system. Raw material homogenization system plays the last key role in stabilizing raw material composition in pit. 4. Preheating decomposition
--Raw materials and fuel preparation Energy used in preparing the raw material consists of preblending (prehomogenization and proportioning), crushing, grinding and drying (if necessary) the raw meal which is mostly limestone. All materials are then homogenized before entering the kiln.
RAW MATERIAL GRINDING The raw material grinding is a process, which involves preparation of raw mix for making clinker. The crushed limestone along with the additives such as laterite, bauxite or iron ore in the required proportions are ground raw mills for getting raw meal of required fineness.
